mac80211: implement the proactive PREQ generation
Generate the proactive PREQ element as defined in
Sec. 13.10.9.3 (Case C) of IEEE Std. 802.11-2012
based on the selection of dot11MeshHWMPRootMode as follow:
dot11MeshHWMPRootMode (2) is proactivePREQnoPREP
dot11MeshHWMPRootMode (3) is proactivePREQwithPREP
The proactive PREQ is generated based on the interval
defined by dot11MeshHWMProotInterval.
With this change, proactive RANN element is now generated
if the dot11MeshHWMPRootMode is set to (4) instead of (1).
